IPC: G06F13/00
Filed: 1980-02-26
Abstract: PURPOSE:To improve the processing performance of a central processing part by interrupting the central processing part when an excellency signal shows defection during a read of return data. CONSTITUTION:Information is sent to device 13 to be controlled via input-output interface part 12 by the output instruction of central processing part 11. On the basis of this information, device 13 to be controlled operates and sends an excellency signal regarding its operation result and return information to input-output part 12. Then, central processing part 11 counts the time until the excellency signal from device 13 to be controlled is sent back to input-output part 12 after the output instruction. When the excellency signal is not returned from device 13 to be controlled in a certain time, input-output part 12 discriminates defection and interrupts central processing part 11 via interruption line 21. Thus, an input instruction for the confirmation of the excellency signal from central processing part 11 can be omitted, so that the processing performance of central processing part 11 is improved.

IPC: H04B10/118
Filed: 1992-01-13
Abstract: PURPOSE:To obtain the transmission system in which 2-way communication is attained with a single light emitting element. CONSTITUTION:An information signal entering a master set 1 is a modulation signal by a modulator 3, which drives a light emitting element 4 and it sends a signal light toward a light receiving element and a corner cube 7 of a slave set 2. Since the light striking with the corner cube 7 is reflected by a master set 1, the optical axis is adjusted by adjusting the direction of the master set so as to maximize the respectively level of the master set 1. On the other hand, the signal light made incident in the light receiving element 5 of the slave set 2 is detected by the light receiving element 5 and the information signal is reproduced by a demodulator 6. The information signal entering the slave set 2 is modulated by a modulator 8 to control an optical shutter 9. Since the light from the master set 1 is made incident in the corner cube 7, the modulation signal light is sent to the master set 1 by controlling the reflected light with the optical shutter 9. The master set 1 receives the light by the light receiving element 10 and the light is converted into an electric signal and a demodulator 11 reproduces the information signal.

Title: Double surface grinding method for sheet-like work
Inventor: TSUSHIMA YASUTO
IPC: B24B7/17
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To grind both sides of a sheet-like work precisely by holding it in position with no shifts from a reference support position. SOLUTION: The grinding method supports both sides of a semiconductor wafer W for rotation and feeds a pair of grinding wheels 1 and 2 for grinding to grind both the sides of the wafer W simultaneously. After the left grinding wheel 1 normalized is fed for grinding and stopped at a reference position Z, only the right grinding wheel 2 is left fed for grinding. Because the grinding surface of the normalized grinding wheel 1 serves as a reference wafer-grinding plane, the wafer W is continuously held stable at the reference position Z irrespective of the progress of the grinding process so as thus to have both its sides ground precisely with no deformation.
